Hyperspeed Planets Are Hurtling Out of the Milky Way?

If you think life on Earth moves too fast, imagine being perched on a planet that’s hurtling through space 400 times faster than our home world.

According to a new study, astronomers predict that “hypervelocity planets” are streaking through our Milky Way galaxy at up to 30 million miles (48 million kilometers) an hourâ€”flung from the center of our galaxy by so-called gravitational slingshots.

Only subatomic particles such as cosmic rays are known to reach higher speeds in the Milky Way. (Related: “Lightning Creates Particle Accelerators Above Earth.”)
